Hydraulic vehicle assembly for carrying cruise ship stage frame structure and hydraulic vehicle

The invention provides a hydraulic vehicle assembly and a hydraulic vehicle for carrying a cruise ship stage frame structure, and the hydraulic vehicle assembly comprises a rigid body assembly, a first fixed connecting piece, a second fixed connecting piece and a supporting plate. The first fixed connecting piece is fixedly connected to one side of the bottom of the rigid body assembly and used for limiting a first pallet fork structure of the hydraulic vehicle. The second fixed connecting piece is arranged on the side, away from the first fixed connecting piece, of the bottom of the rigid body assembly in a position-adjustable mode and used for fixing the rigid body assembly and a second pallet fork structure of the hydraulic vehicle; the supporting plates are a set of rotatable supporting plates fixedly connected with the rigid body assembly and used for increasing constraint in the length direction for the cruise ship stage frame structure. According to the technical scheme, the stage frame structure can b
